NEW YORK — For many, PBS is known as the 44-year-old public television network home to series such as Sesame Street, PBS NewsHour and Downton Abbey.

However, the public broadcaster has quickly grown into a formidable creator in the YouTube space with PBS Digital Studios recently surpassing 1 million subscribers. Monday, at the network's first Digital Content NewFront presentation, PBS added four digital series to its lineup of more than 30 shows.

PBS will debut its first scripted series, Frankenstein M.D., later this year. The series comes from Pemberley Digital, the creators of the popular, Emmy-award winning series Lizzie Bennett Diaries, which adapted Jane Austen's Pride and Prejudice using the 100 online video diaries of the titular character. Using a similar approach, Frankenstein M.D. will adapt Mary Shelley's classic novel through videos focusing on the medical experiments of "obsessive, eccentric prodigy" Victoria Frankenstein. Eight episodes will roll out each month.

Launching today are new series Bongo Bongo and Food Buzz, both produced in partnership with Magnet Media. Bongo Bongooffers history lessons on English language words. The first episode features host Ethan Fixell, in YouTube's patented fast-talking, jump-cut heavy style, explaining the etymology of the word rant.

Food Buzz focuses on the latest trends in the food blogosphere and the history behind food memes. The first episode takes a deep dive into the Internet's most popular condiment — Sriracha.

PBS also announced a reboot of director Scott Stuckey's quirky musical variety show, Pancake Mountain. At the presentation, PBS offered a glimpse at the reboot with comedian Reggie Watts singing his own rendition of The Carpenters' song Close to You accompanied by a goat puppet.
